Anyone used them? Anyone have comments on them other than they are single solenoid? I have pretty much written off worrying about the supposed issue with ABS and single solenoid systems. Too many people using too many different brands of systems for them to have issues and the boards not be flooded with posts about it. So.. like I said. Other than having comment about it being a single solenoid system does anyone have any experience with the SLP line locks? They are on Summit's site for $155. Part number is is SLE-M25001. They appear to come with pre-bent lines, wiring, solenoid, fittings,and a switch.
